These are similar procedures in that they involve sutures to adjust or restore the "angle of His" or oesophagogastric angle. Similar to RefluxStop but without the silicon ball.
Wilhelm His, a Swiss German anatomist who lived in the late 19th Century, discovered the angle formed between the oesophagus and the fundus of the stomach was a factor in permitting acid reflux. The wider the angle, the more likely for reflux to occur.
1. Body of the stomach; 2. Gastric fundus; 3. Anterior wall; 4. Greater curvature; 5. Lesser curvature; 6. Cardia; 9. Pyloric sphincter; 10. Pyloric antrum; 11. Pylorus; 12. Angular notch; 13. Gastric canal; 14. Gastric folds
We demonstrated that as the angle of His becomes wider the esophago-gastric orifice area becomes larger. Additionally, a wider angle of His and a larger esophago-gastric orifice area were correlated independently with more reflux. This suggests that the fundoplication creates an acute angle of His which is correlated with a smaller area of the esophago-gastric orifice and eventually with a lower incidence of reflux.

Fundopexy is a surgical procedure that involves attaching the fundus of the stomach (the upper, curved part) to the diaphragm or other structures to prevent its displacement with the purpose of treating reflux by reinforcing the barrier between the esophagus and stomach and preventing hiatus hernia.
(In the diagram, the fundus is stitched to the oesophagus endoscopically.)

Gastropexy is a surgical procedure where the stomach is stitched to the abdominal wall or diaphragm to secure the stomach in place and prevent abnormal movement to treat recurrent hiatal hernias.
It is modified from a Bicorn procedure to stop the stomach twisting which didn't involve retracting the hiatus hernia first.

Fundopexy specifically involves the fundus of the stomach and is often used to treat GERD or hernias related to the esophagus-stomach junction.
Gastropexy is a more general term for suturing the stomach to the abdominal wall, primarily used to prevent the stomach from twisting (volvulus) or from abnormal displacement, especially in the case of hernias.
